Object name: ARP255
Arp 255 is another in his category Galaxies (not classifiable as S or E); Appearance of fission. In this case, it does look as if an arm broke off though that is likely only illusion. Even Arp considers it a separate galaxy but does believe the faint tidal arm to the north is really the continuation of an arm of the bigger galaxy as he notes: "Faint arm extends beyond high surface brightness companion." The pair is otherwise known as UGC 05304. They show a red shift indicating a distance of about 565 million light-years. NED calls the smaller one a "late spiral" and the larger simply S? probably indicating there's no agreement as to what type of spiral it is rather than if it is a spiral as it is obviously one. Looks rather like SBc pec to my untrained eye. The arms are unusually red for a spiral except for a detached very blue segment that may be mostly massive star clusters but otherwise, show no visual hint of star formation due to the interaction. Though it may be hidden behind dust. There seems to be little on this pair. Down and to the right of the pair is CGCG 035-075 which has about the same redshift and is obviously part of the same galaxy group. Directly west past an orange star is a rather bright very blue "star". It is the quasar [HB89] 0950+080 at 9.3 billion light years. Directly below CGCG 035-075 is a large faint, nearly colorless smudge of a galaxy. It is LSBC D709-10, an irregular Magellan like galaxy about 150 million light-years distant.
